    Red face Lame - MySql error 2003 (cannot connect 10061)

    Hi folks... I got into a desperate problem. My MySQL Server 5.1 does not want to connect on my Windows 7 platform. It was working all well until few days ago I added a line in the my.ini configuration file: I just added: default-character-set=utf-8. I have removed that line again and still I cannot get the Server connection. I also reverted to a backup of the .ini files there was in the directory, and still nothing

    The ini file reads as follows:

    Code MySQL:
    # MySQL Server Instance Configuration File
    # ----------------------------------------------------------------------
    # Generated by the MySQL Server Instance Configuration Wizard
    #
    #
    # Installation Instructions
    # ----------------------------------------------------------------------
    #
    # On Linux you can copy this file to /etc/my.cnf to set global options,
    # mysql-data-dir/my.cnf to set server-specific options
    # (@localstatedir@ for this installation) or to
    # ~/.my.cnf to set user-specific options.
    #
    # On Windows you should keep this file in the installation directory 
    # of your server (e.g. C:\Program Files\MySQL\MySQL Server X.Y). To
    # make sure the server reads the config file use the startup option 
    # "--defaults-file". 
    #
    # To run run the server from the command line, execute this in a 
    # command line shell, e.g.
    # mysqld --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini"
    #
    # To install the server as a Windows service manually, execute this in a 
    # command line shell, e.g.
    # mysqld --install MySQLXY --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini"
    #
    # And then execute this in a command line shell to start the server, e.g.
    # net start MySQLXY
    #
    #
    # Guildlines for editing this file
    # ----------------------------------------------------------------------
    #
    # In this file, you can use all long options that the program supports.
    # If you want to know the options a program supports, start the program
    # with the "--help" option.
    #
    # More detailed information about the individual options can also be
    # found in the manual.

    #
    # CLIENT SECTION
    # ----------------------------------------------------------------------
    #
    # The following options will be read by MySQL client applications.
    # Note that only client applications shipped by MySQL are guaranteed
    # to read this section. If you want your own MySQL client program to
    # honor these values, you need to specify it as an option during the
    # MySQL client library initialization.

    # set it too high.

    # Size of each log file in a log group. You should set the combined size
    # of log files to about 25%-100% of your buffer pool size to avoid
    # unneeded buffer pool flush activity on log file overwrite. However,
    # note that a larger logfile size will increase the time needed for the
    # recovery process.
    innodb_log_file_size=24M
     
    # Number of threads allowed inside the InnoDB kernel. The optimal value

    Please help me to get back the MySQL connection.

    I solved the problem.... in a nut shell:

    In MySql Administrator Utility, I went to Startup Variables, and then to Advanced Tab. There I had Def. Char Set ticked to UTF-8. I removed the tick, applied changes and then the connection was successful.

    and furthermore, to have the default charset variable set to utf-8, the variable had to be written as "utf8" not "utf-8". The hyphen caused the error.
